STRUCTURE OF DIBROMODIOXOURANIUM(VI)- TRIS(TETRAHYDROFURAN)
(UO-2Br-2).3C-4H-8O, M-r = 646.17, monoclinic, P2-1/c, a = 6.931 (3), b = 17.032 (4), c = 16.257 (4) ALPHA, beta = 94.25 (5) degrees, V = 1914 (2) ALPHA3, Z = 4, D-x = 2.242 g cm-3, lambda(Mo Kalpha) = 0.71073 ALPHA, mu = 121.920 cm-1, F(OOO) = 1192, T = 295 (1) K, R = 0.037 for 965 observed reflections. The coordination polyhedron of the U atom is a bipyramid with a non-planar pentagonal base made up of two Br ions and three THF O atoms. The two uranyl O atoms are in the apical positions. The stacking in the crystal is dictated by van der Waals interactions.
